Yesterday I presented at NoSQL Now! 2013 in San Jose, CA, on how Castlight Health uses MongoDB to support low latency geospatial searches on huge amounts of health care pricing data. Given the number of parallel tracks and the total number of people attending sessions, I was pleased to get about 50 engaged people in… Read More »
My presentation at MongoDB Days SF on Friday went very well, though I got to the last slide of my 40-minute talk in just 30 minutes. Hopefully, I didn’t speak too fast for a lot of people. Fortunately, I remembered at the end that I had also wanted to talk about how I saved space… Read More »
I’m very excited that my talk proposal “Geo Searches for Healthcare Pricing Data” was accepted for MongoDB SF 2013. I’ll be speaking at 11:55 am on May 10th in the Palace Hotel Gold Ballroom about why I chose to deploy MongoDB at Castlight Health to serve large amounts of healthcare pricing data with very low… Read More »
10Gen put on another excellent MongoDB conference last Friday, this time at Microsoft Research in Mountain View. Like Mongo SF, there was a good balance between intro and advanced material, as well as between 10Gen presenters and third party presenters, like myself. Registration was smooth, sessions ran on time, they made it easy on presenters,… Read More »

Interest in the conference has soared and 10Gen is now expecting 500 attendees. Just a week ago, they were at 300 attendees. They had to add a fourth track of talks to handle… Read More »
Monitoring MySQL with Cacti Cacti, like many other tools (Munin, Cricket, etc.), is a wrapper around RRDTool Baron feels that existing tools (zabbix, ZenOSS, OpenNMS, etc.) that try to do graphing and alerting do at least one of them poorly, though Reconnoiter looks promising. Cacti does graphing well RRDTool does interpolations, so you lose the… Read More »
Replication Tips – slides Single master can typically handle a few dozen slaves If you have a lot of slaves and want to do filtering for all, maybe use blackhole engine to do filtering in one place. Especially if running blackhole slave on same server to limit network bandwidth. Replicate over WAN – slave_net_timeout, master_connect_retry,… Read More »
What’s New in MySQL 5.5? Performance Unleashed! – slides Default storage engine is InnoDB (what had been called the InnoDB plugin, but now is the only version). Many locks and mutexes held back scalability in 5.1. Biggest win was fixing uses of LOCK_open. It was used for many things, some of which made no sense. Introduced… Read More »
I’ll be in Portland on November 13, 14 and 15 for OpenSQL Camp, an unconference covering open source databases. In addition to learning more about MySQL and Drizzle internals, I’m looking forward to learning a bit about Postgres and some of the NoSQL database alternatives. They aren’t just your father’s high performance key-value stores, anymore.
I went to JavaOne last week and was once again amazed by the number of attendees. I heard someone say 15,000 people had registered. I believe it. Other programming languages like Python and Ruby might be gaining in popularity on Java, but Java is still pretty dominant. And just like last year, the queues for… Read More »
